Texas is pushing forward with plans to make parts of the Bible required reading in public classrooms

6. Education, like elections, is left to the states according to the Tenth Amendment, which leaves the responsibility

of establishing, funding, and regulating public schools to individual states.

All states' curricula are decided by the public through their state boards of education.
If this is a state board of ed decision, it can stand constitutional scrutiny. But parents have recourse. If parents don't want their children exposed to bible texts, they have the right to have their children read other texts, and principals are bound to honor parents' wishes, since Bible readings are not revealed here to be core graduation requirements. If they are, parents could get alternative readings, even though state boards of educations have approved Bible texts.

Overall, the separation of church and state is an idea derived from the First Amendment (The actual phrase originated from a private letter written by Thomas Jefferson to the Danbury Baptist Association in 1802. In it, he described the First Amendment as building a "wall of separation between Church & State" ), but his phrasing is not literally a written part of US founding documents.

It's not a done deal if a plaintiff with standing (maybe a teachers' statewide organization, or a statewide parents organization) files against the decision in the courts.
